Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80712, here are decompositions:

  • 11 + 80701 = 80712
  • 29 + 80683 = 80712
  • 31 + 80681 = 80712
  • 41 + 80671 = 80712
  • 43 + 80669 = 80712
  • 61 + 80651 = 80712
  • 83 + 80629 = 80712
  • 101 + 80611 = 80712

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80712 first appears in π at position 85,275 of the decimal expansion (the 85,275ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
